AIR-COOLING' DEVICE.

y Specification of Letters Patent.

Patented Dec. lid, 1915.

Application filed-October 1, 1914. Serial No. 864,392.

To all whom it 'may concern:

Be it known that I, JOHN E. COCHRAN, a citizen of the United States,residing at San Diego, in the count-y of San Diego and State ofCalifornia, have invented certain new and useful Improvements inAir-Cooling Devices, of which the following is a specilication.

My invention relates tov air cooling devices and has for its object theprovision of a device adapted for attachment to an ordinary electric fanand so arranged that the blast of air from said fan will cause movementof a carrier which will present within the path of said air successivelayers of water by which the air is cooled.

Further objects and advantages of the invention will be setl forth inthe detailed description which now follows Y ln the accompanyingdrawing: Figure 1 is a side view of the device showing it mounted upon afan. Fig. 2 is a detail view of the water retaining casing, and Fig. 3is a detail view of the rotative carrier, hereinafter described.

Like numerals designate corresponding parts in all of the figures of thedrawing. Referring to the drawing the numeral designates an ordinaryelectric fan comprising the usual skeleton guard frame 6 and fan blades7. The invention resides in an attachment for such fan comprising a ringor band 8 of sheet metal such as tin having its sides partially closedby plates 9 which together with the band constitute a water receivingcompartment 10.

A bearing post 1l is carried byone of the plates and serves as amounting for a rotative carrier 12 comprising a' hub 12, a peripheral-band 13 and foraminous radial vanes 14 extending therebetweenpreferably formed of Wire gauze and set at such an angle that the blastof air from the fan will cause the carrier to rotate. Therefore as theblades 14 are successively passed through the water contained in thecompartment 10 they elevate a limited amount of water in the form of afilm into the path of the blastv of air from the fa-n. through this filmof cooled.

It is a well known fact that it is not desirable to permit the blast ofa fan to blow directly upon a person and many devices have been inventedfor deflecting the blast from a direct path. rlhe hereindescribed devicewill eliiciently serve such purpose and will at the same time utilizethe power exerted by the blast when its direction of movement is changedto elevate the film of water as hereinbefore set forth.

To hold the attachment in place a piece of wire is provided the bightportion of which is passed through holes 15 formed in The air in passingband 13 and the terminal ends of which arev bent to hook formation at 16and engaged with the rear edge of the skeleton guard frame 6. Y v

'hlle the elements shown and described are well adapted to serve thepurposes for which they are intended it is to be understood that theinvention is not limited to the precise construction set forth butincludes within its purview such changes as may be made within the scopeof the appended claim.

Having described my invention what I claim'is:-

rlhe combination with an electric fan and its usual skeleton guard of awater receptacle comprising a band and plates partially closing thesides thereof, hooks carried by said band and engaged with said guard tosecure the receptacle to the front of the fan, a bearing post carried bythe receptacle and a rotative carrier journaled upon the bearing postand comprising an annular rim and a plurality of vanes set at an angleto the line of blast from the fan, `said vanes being formed of wiregauze.

In testimony whereof ll affix my signature in presence of two witnesses.
